When you've got two monitores with different resoultion, the virtualsize
is not correct. It's always the bigger one. You can only correct this,
if you open a console and type "xrandr --output VGA-0 --auto". You have
to do this every time you login.

As I said, please send the whole ouput of xrandr --verbose before and
after running the above xrandr --auto.
I can't get the correct resolutions again. Also xrandr --output VGA-0 --auto doesn't work any more even though I used the old config. At the moment the picture from the big monitor (DVI) laps over on the small. It's like a small part of the desktop is cloned.

Direct rendering only works, if you have two displays with the same
resolution. Also, you don't get debugging information from glxinfo.

Please send the output of
  LIBGL_DEBUG=verbose glxinfo
when if fails.

Direct rendering seems to work now, but I don't know why:
